LEWIS W-ERTZ, OF OREGON, ILLINOIS.

COM POUND WATER-WHE'EL.

`lPECIFICA'ITION forming part of Letters Patent No. 501,123, dated July 11, 1893.

Application tiled October 15,1892.

To all whom it may concern:

Be it known that I, LEWIS WERTZ, a citizen of the United States of America, residing at Oregon, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Compound Water-Wheels, of which the following is a specification.

p My invention relates to certain improvements in water-wheels, or rather in certain` combinations thereof with a view to constructing what I call a compound water-Wheel, the purpose of which is to obtain from a given volume and head of water more power than can be obtained from a single wheel.

My invention is illustrated in thedrawings by means of two figures, of which- Figure 1 is a vertical diametrical section o f a penstock and three water wheels therein; and Fig. 2 is a horizontal section in line 2 2, of Fig.l.

In the drawings, the penstock is lettered A, the intake, a, and the discharge, c. Extending across the interior of the penstock` are two spiders, a2, a6, in which is journaled a shaft, B. The interior of the penstock is also provided with three horizontal internal flanges, as, c4, d5. Fast upon .this shaft are three wheels, O, O', O2, which may be of any preferred form of submerged wheel. The penstock is made up' of four sections, c6, a7, as, a9, secured together by means of flanges, al, au, cl2, so as to make an air-tight casing from top to bottom. The issue, c2, of the wheel, O2, is larger than the issue, c', of the Wheel, O', which, in turn, is larger than the issue, c, of the wheel, O.

In operation, the water is let through the Serial No. 448,955. (No model.)

intake, a, and soon fills the ventire penstock from top to bottom driving out all the air therefrom, after which it is obvious that the pressure of the wafer upon the three wheelswill be substantially the same for the reason that the water'which is below the upper wheel,

but still within the air-tight penstock, will I claim as new and desire to secure by Letters Patent- The combination of an air-tight penstock, a shaft journaled therein, two or more wheels fast upon this shaft'and having issues of increasing size one after the other, a series of air-tight partitions separating said wheels and suitable inlets and outlets whereby the water is supplied to the penstock, passed first through the wheel having the smallest issue and then in turn through the wheels having issues of increasing size and finally discharged at the outlet; substantially as described.
